Our expertise

The whole vertical, not one layer of it.

Most providers touch one layer of the stack. We architect, migrate, and operate the full vertical — so accountability sits with one partner, not four.

VMware → XenServer migration

The hypervisor exit planned, sized and executed — with the VDI layer taken across, not left behind on the old stack.

NetScaler architecture, upgrades & automation

HA pairs designed and upgraded, gateway and load-balancing configuration troubleshot, and the repetitive parts automated over NITRO.

Citrix DaaS & hybrid delivery

Cloud Connectors, hybrid resource locations and on-prem VDAs delivered and monitored as one estate, not two.

Lead practice

Cloud architecture & migration

Hybrid and multi-cloud design, datacenter exits, and cost-and-performance optimization for workloads that can’t afford downtime.

  • AWS
  • Landing zones
  • Hybrid networking
  • FinOps

Virtualization & VDI

Hypervisor strategy and the post-VMware question answered honestly — including VMware-to-XenServer migration, consolidation, and VDI that users don’t fight.

  • Hyper-V
  • VDI
  • Migration

Citrix & NetScaler engineering

Custom automated deployments and ongoing monitoring for Citrix estates — on-prem, DaaS, or hybrid — with NetScaler architecture, firmware upgrades, gateway troubleshooting and automation as part of the same practice.

Monitoring & observability

End-to-end visibility across the stack so problems surface before users call — with AI-assisted triage that correlates signals and points to the likely root cause, instead of leaving your team to chase alerts.

  • AI-assisted triage
  • Root-cause analysis
  • Dashboards
  • Alerting
  • Capacity
Resilience

Backup & recovery

Reliable, tested backup and disaster-recovery built on Veeam — so a ransomware hit, a failed migration, or hardware loss is a recoverable event, not a crisis.

  • Veeam
  • Backup design
  • DR planning
  • Recovery testing
  • Retention
Security

MFA & identity

Multi-factor authentication and secure access rolled out across your environment — with Duo, Okta, or Microsoft Entra, integrated cleanly with the apps and desktops your people use.

Our own software

We build the monitoring platform we deploy.

DTR Vantage is our own product, developed in-house and running in customer environments today. It is what our monitoring and managed-support engagements are built on — which is why an engagement ends with working visibility rather than a diagram.

  • Citrix sessions, explainedWhy a session is slow or a launch failed — from the VDA and from the NetScaler Gateway at once: ICA round trip, logon duration broken into its phases, and the HDX records the appliance itself exports.
  • NetScaler, XenServer and Windows in one placeHealth, certificates, configuration and consoles for NetScaler HA pairs, XenServer pools and Windows servers — read and managed from one screen.
  • Self-hosted by defaultIt runs on one Windows VM inside your network. Nothing leaves it unless you switch a cloud option on, and every panel says when it could not read something rather than showing a zero.

How engagements run

A structured methodology, built around your team.

We augment your engineers and leave them with documentation and a stack they can run — not a dependency.

01 / Assess

Assess

Architecture review of the current estate, risks, and the real cost of the status quo. NDA-friendly from day one.

02 / Architect

Architect

A target-state design with migration path, rollback plan, and decisions documented for your team to own.

03 / Deploy

Deploy

Hands-on delivery through custom automated builds — phased cutover and validation against agreed criteria.

04 / Manage

Manage

Monitoring stood up across the stack, with handover or ongoing managed support — your call.

Recent work

Three problems, and what actually fixed them.

Client names withheld. Each of these was found, fixed and verified on a live estate — the figures are the ones in the engagement record.

Citrix Gateway · security

A credential spray nobody could see

Environment
A multi-site NetScaler estate — 12+ HA pairs on 14.1, gateways published to the internet.
Problem
Failed sign-ins were buried in the syslog, with no way to tell an attack from a forgotten password — and nothing acted on them.
Work
Scored the gateways’ own sign-in failures and had the appliance block the source itself, using its native responder policy rather than a device in front of it.
Result
278 failed sign-ins from one address against 52 accounts, identified and blocked at the appliance — with the change on record in the configuration log.
RD Gateway · root cause

“The logon attempt failed” — with the right password

Environment
Remote Desktop Gateway with RD Web Access, published for remote staff.
Problem
Users authenticated successfully and were then refused. The gateway’s own log recorded nothing at all.
Work
Traced it to a site-level HTTP redirect inheriting into /rpc, so the RPC proxy answered a 302 after the sign-in succeeded — one configuration property, invisible from the gateway console.
Result
Fixed the same day, and turned into an automatic check so the same misconfiguration is caught on every server we monitor.
Citrix · session quality

Session metrics that never arrived

Environment
Citrix Gateway exporting AppFlow to a collector, for HDX session visibility.
Problem
Launches were visible, but the per-session quality figures — round trip and bandwidth — never appeared, so slow sessions could not be proved either way.
Work
Decoded the appliance’s own export and found the AppFlow policy bound at REQUEST only; bound it at ICA_REQUEST as well.
Result
Round trip and bandwidth per session from the next launch onward, confirmed against the capture rather than assumed.

Happy to walk through any of these in detail, under NDA, on the first call.

Industries we serve

Manufacturing & logistics

Standardized, automated deployments across distributed sites, keeping operations running without an oversized IT team.

Professional services

Secure remote access and reliable virtual workspaces for distributed, client-facing teams that can’t afford lag.

Enterprise IT at scale

Large, complex estates where consolidation, cost control, and resilient architecture move the needle most.

Common questions

What to expect working with us.

Will you work alongside our internal IT team?

Yes — that’s the default. We augment your engineers, document every decision, and hand over a stack your team can own. The goal is capability, not dependency.

Do you only work with Chicagoland companies?

We’re headquartered in the Chicagoland area and serve enterprise clients nationwide. Engagements are delivered through a structured methodology regardless of location.

What does an initial consultation include?

You talk directly with an architect who reviews your current cloud, virtualization, or Citrix environment, discusses your goals and constraints, and outlines where the real risks and opportunities are — NDA-friendly, with no commitment to proceed.

Do you offer ongoing managed support?

Yes. After deployment you can take full handover, or we can provide continued monitoring and managed support in a co-managed or fully managed model.

Start here

  • NDA-friendly. We can sign before you share architecture details.
  • Response within 24 hours. Usually a real answer, not a calendar link.
